derivative) an alkenyl halide. The reactivity of each functionality in these derivatives has been explored, and the usefulness of these substrates has been demonstrated with the preparation of furanose-based carbohydrate templates with up to four sites of molecular diversity.
高度官能化的 1-exo-alkylidene-2,3-anhydro-, 和 1'-halo-1-exo-alkylidene-2,3-anhydrofuranose 可以分别通过四步或五步从 D-甘露糖制备。这些化合物具有多种官能团,包括双键、环氧乙烷、烯丙基环氧乙烷和(在 1'-卤代衍生物的情况下)烯基卤化物。已经探索了这些衍生物中每个功能的反应性,并且通过制备具有多达四个分子多样性位点的基于呋喃糖的碳水化合物模板,证明了这些底物的有用性。
